CVE-2009-2336: WordPress

Medium severity, CVSS 5.0. EPSS: 5.4% chance of exploitation in the next 30 days.

The forgotten mail interface in WordPress and WordPress MU before 2.8.1 exhibits different behavior for a password request depending on whether the user account exists, which allows remote attackers to enumerate valid usernames. NOTE: the vendor reportedly disputes the significance of this issue, indicating that the behavior exists for "user convenience."

Affected products

• WordPress WordPress: before 2.8.1 (fixed in 2.8.1)
• WordPress WordPress Mu: before 2.8.1 (fixed in 2.8.1)
